TYPE FURNITURE AND TYPE-FURNITURE MOLD.

Application filed August 21,

- To all who mz't may concern."

Be it known that I, Asnrox G. S'rnvnnsox, a citlzen of the Un ted Statesof Amer- 1ca, residlng at hew iorkcity; State and county of New York.have invented a new and useful Type Furniture-and T ype-Furniof whichthe following is a specicasting type furniture so-called on intertype,

i a piece of type furniture.

strong and. durable.

linotype and similar machines. The apparat-us is designed'to cast typefurniture from two ems pica upward.

My 'invention aims at producing a uni-' formly satisfactory product, thefurniture when finished being comparatively light yet To that end Iproduce a mold the core of which is properly constructed and-reinforcedso that it will not warp, bend or break during the casting operation.'The means and method which I have designed and employ in thepractising. of the method is more fully described in the accompanyingapplication and is illustrated in the accompanyingdrawings, in which:

Figure 1 is a perspective view of a mold with the closure or front pieceremoved.

F'g. 2 is a relatively enlarged front elevation of the same parts withthe portion of the front in place.

Fig. 3' is a cross section on the line 33.

Fig. 4 is a plan view of a detail broken away.

Fig. 5 is a )erspective'view of another detail broken away.

Fig. 6 is a horizontal section of a part of Fig. 7 is an edge elevationof the pieceviewed from above.

Fig. 8 is a view similar to Fig. 4 showing" modification.

It will be understood that I have shown my new apparatus only in itspreferred form and that it is capable of a wide variety of modificationswithout departing. from the spirit or scope of the invention.

The mold comprises the usual body 10 which is adapted. to be secured toor mounted upon the ordinary wheel or disk in the usual man ner.' 11 isa cap or cover mounted in any suitable way on the body 10. In the spacewithin the mold body 10 where the slug is to befcast, is located a core12, the upper and lower sides of the core being spaced apartSpecification of Letters Patent.

from the corresponding walls of the mold body so as to form at the rearan upper and a lower slot through one of which the molten metal underpressureis introduced when a piece of furniture is to be'cast.- The coreis preferably tapered or beveled transversely,

and at its forward or narrower edge I form slots or notches exteiidlngtoward the rear edge of the core, the sides of the slots flaringoutwardly. Thus, when molten metal is in troduced that part of themolten metalstanding in the said notches will form transverse supportingbridges between the two opposite sides of the furniture. In general, theparts I have thus far described are well .known but are not practical ofemployn'lent in producing a piece of furniture of greater length thanabout 13 ems pica, because the pressure of themolten metal at the rearedge of the core will buckle and distort the same producing imperfectand unsatisfactory work. To prevent this, and'to permit of forming apiece of furniture ofany desired length, I provide suitable means toeffectively prevent the aforesaid buckling of the core. '14 represents aremovable front piece or closure for the nif old which piece is carriedby a matrix 15 preferably in the form of 'a block which may besupported-b the matrix carrier in the usual manner.

This closure piece 11 is provided with a face piece 16 which extendsinto the mold body to form a front core. the side walls of, said face 16being substantially beveled to permit the metal to flow into the spacearound said piece and between the same and the walls of the mold body,whereby said face piece will act as a core. At the front edge of thecore 12 between the notches therein I provide pins or other suitableprojections 1818 which when the mold is assembled in place ready for useengage the flat or supporting surface of the piece 16 which latter thenconstitutes a reinforcing abutment for the core 12 in addition to itsaforesaid functiom hence, when the pressure of the molten metal isapplied to the rear edge of'the core 12 it cannot possibly buckle, bendor distort the 'same by reason of the weaknesses thereln produced by thenotches, and hence, the slugs or furniture produced W111 be u-n1- formlyaccurate. The cores 12 and 16 serve to displacesuflicient metal to makethe farm- 'ture comparatively light without sacrifice to strengthbecause of the reinforcing or bridging bars iii-19 which unite theopposite sides of the same.

Instead of forming relatively small pin like projections 1818 along thenotched edge of the core 12, I may actually make those portions of thecore between the notches of sullicient length to actually en gage theface piece 16 when the parts are assembled so as to get a directreinforce-- ment, instead ofuan indirect reinforcement through themedium of the pins 18. In some-instances this modification, Whichisillustrated in Fig. 8, is preferable. It is ob vious that the corepieces 12 and 16 may be made of various shapes and sizes so thatdifferent ones can be substituted. in this instance, the piece, whichcarries the core piece or projecting portion 16 is detachably connectedto the matrix or quad block by a dovetail joint that permits the readysubstitution of other face pieces.

A piece of furniture constructed by my improved mold possesses thefurther advantage of permitting gasolene or other clean-- ing agentemployed to drain through the passages between the bridges 19 19, saidpassages being formed during the making of the furniture as a result ofcausing the notched edge of, the core 12 to bear against the face 16during the molding operation. As a result, my intention resides notalone in the means and method of casting the furniture, but also in thefurniture itself.

I claim:

1. In a mold of the character described, a mold body having a passagetherethiough,

closure means for the front end of said passage and a core for partiallyclosingthe rear end of said passage, the forward edge of said core beingnotched, those parts of the corebetween certain notches being supportedby said closure.

2. In a mold of the character described, a mold body having a passagetherethrough, closure means for the front end of said passage and a corefor partially closing the rear end of said passage, the forward edgemasses of said core being notched, those'parts of the core betweencertain notches being sup ported by said closure, said means comprisingprojections at the inner edge efsaid core.

3. In a mold of the character described, a mold body having a passagetherethrough, closure means for the front end of said pas sage and acore for partially closing the rear end of said passage, the forwardedge of said core being notched, those parts of the core between certainnotches being supported by said closure, the closure means for the frontend ,of said mold projecting partially into the space intlie-mold bodyto act as a core. j j 4. In a mold of the character described, a mold.body having a passage therethrough, a closure for the front end of saidpassage, :1 core held Within the rear end of the passage and partiallyclosing the same, and the forward end of said corecontacting with. thefront closure at longitudinally spaced points.

5. In a mold of the character a mold body having a passage extendingtherethrough from front to rear, aremorable closure for the forward endT the passage, and a fixed core Within the rear end of the passagepartially closing the same, the forward end of the core contactingwiththe front closure at predetermined points for support thereby.

6. In a mold of the character described, a mold body having a passageextending therethrough from front to rear, a closure for the front endof the passage having a central longitudinal core-like projection cictending within the forward end of the passage, a core held Within therear end of the passage and providing a similar opposed cen- .trallongitudlnal member, the inner ends of said member and projection beingseparated and the opposed faces thereof being formed for contact witheach other on reduced areas- I ASHTQN G.
